OGX Thick & Full Biotin & Collagen Shampoo is a go-to if you want that fuller, more voluminous hair vibe. The purple-and-gold packaging instantly stands out in the shower and feels sleek yet sturdy. The texture is lightweight but creamy enough to work into a satisfying lather that doesn't weigh hair down. The scent is fresh with a slightly sweet, salon-like finish that makes washing your hair feel like a mini treat. Performance-wise, it delivers noticeable body and bounce, leaving fine or flat hair looking thicker and healthier after just a few washes. The blend of biotin, collagen, and wheat protein really helps give strands that fuller appearance without stripping moisture. For the price, the value is solid — it feels way more luxe than its drugstore tag.

OGX Beauty Biotin & Collagen Shampoo is designed to add volume and thickness to fine or thinning hair. Infused with biotin, collagen, and wheat protein, it strengthens strands, promotes fuller-looking hair, and leaves it feeling healthy and nourished.

I have thin, fine hair and was looking for something to give it a boost. This has a great smell and feels luxurious on pouring. It did make my hair feel a little more bouncy but I did find it made my hair feel course. This could be my own hair just not suitable for it. It is a higher priced shampoo but it is effective on the claims it made so for me overall it was good value ☺️

Honestly the shampoo was okay. It smelled really nice, lathered well, made my hair soft. The value for money was also nice as it came in a large bottle. The results of using this shampoo wasn't exceptional. Didn't feel hair growth, it being extraordinarily shiny or thick as advertised. It was okay I have this shampoo in my shower cabinet for guests.

New formula is awful! Note the date of all the reviews on here - they are reviewing the old product/formula not this new shampoo they brought out in 2025. They should not keep the reviews on here as it has changed beyond recognition. A completely different shampoo really! Misleading!

The reason I purchased this product was because of its ingredients. And the value for the money. The scent was wonderful the packaging caught my eye being a nice shiny purple. However the effectiveness, not so great. I didn't really see much of a difference in my hair

I’ve been using OGX Thick & Full + Biotin & Collagen Shampoo for a few weeks now, and I actually like it. It smells really nice, kind of sweet and fresh, and it lathers up well without needing a ton. My hair feels a bit fuller after using it, though I wouldn’t say it’s a dramatic difference. It doesn’t weigh my hair down or leave any residue, which is a plus. Overall, it’s a solid shampoo if you’re looking for something affordable that gives a little volume boost.

Very sad, you had such a great product, and you changed the ingredients. Before it had the purple in it to help with color-treated hair. Now you put these other peptides in, and it totally dries out my hair, and I have no shine. Do you have any the old product left? I can't be the only one complaining..I can't even call you about this

I only tried this once because of its density and gel-like texture, it doesn't do much for my hair, but I don't remember much. I used it many years ago and I remember that it cleaned a lot and didn't leave the hair so damaged, and well, as far as it promises to grow hair, not that much, really.

I’ve been using the OGX Biotin and Collagen Shampoo for a little while now and I really like it. It makes my hair feel thicker and fuller, which is exactly what I wanted. The scent is pleasant and not too strong. It lathers nicely and rinses out easily without leaving any residue. My hair feels soft and looks healthier after using it regularly. Overall, a great shampoo if you want something that helps add volume and strength without breaking the bank.
